CAR-COUPLING.

SPECIFICATION forming part of Letters PatentNo. 482,569, dated September 13, 1892.,

Application led March 7, 1892. Serial No. 424,034. (No model.) Patented in Canada April 4, 1892, No. 38,627.

To a/ZZ whom it may concern:

Be it known that I, JOSEPH HENRY COLE- MAN, of the village of Tottenham, in the county of Simcoe, in the Province of Ontario, Canada, have invented a certain new and Improved Automatic Car-Coupler, (tor which I have obtained Letters Patent in Canada, dated April 4, 1892, No. 38,627,) of which the following is a specification.

The object of the invention is to devise an extremely-simple automatic car-coupler of that class in which is employed an arrowheaded link designed to t into a socket made in the interior of the draw-head, a movable block being inserted into the draw-head in such a manner as to lock the arrow-head of the link in the socket; and it consists in the peculiar construction, arrangement, and combinations of parts hereinafter more particularly described, and then definitely claimed.

In the accompanying drawings, Figure l is a perspective view of my improved automatic car-coupler attached to the end of a box-car. Fig. 2 is an enlarged sectional view of myimproved draw-head with its link locked in. Fig. 3 is a perspective detail of the lockingblock.

In the drawings, A represents the drawhead, which may be made in any desirable design and connected to the car in any suitable manner.

B is a block made any suitable shape and design to iit into a hole of corresponding shape made in the draw-head A, as indicated. A hole b is made in the block B as large as the mouth of the draw-head at one end and reduced at its inner end, so as to be larger than the diameter of the body of the link.

C is a socket made in the inner end of the draw-head A, which socket is made so that the head D of the link E shall be a loose tit. Then the link E enters the mouth of the draw-head A, its head D comes in contact with the top of the hole Z), and as the block B is loose it raises the said block untilthe head D passes it, and entering the socket C, its head being clear of the block B, the latter falls, the hole b permitting the said block to fall down behind the head D, thus locking the said head inside the socket. As the head D of the link E is thus held clear of the block B, the rocking of the link E has no effect upon the block B, as the said block receives and withstands the entire draft. On each side of the path of the link E as it enters the draW- head is a recess c, in which the bottom or legs b of the block B enter, and thus said block is supported at top and bottom by the metal of the draw-head against the pull of the link E.

Various devices may be used for opening the coupler. I illustrate one plan,but do not confine myself to the one shown. In the plan exhibited I show a horizontal rod F, carried in proper bearings on the end of the car G. An arm H extends from the rod Fand is leXib] y connected to the block B, as shown. The arm H is connected to the crank-lever I, pivoted on the top of the car G. In this Way the block B may be raised either from the top of the car or from either side of it.

That I claim as my invention is- The draw-head A, having recesses a and a socket C made in it, in front of which is placed a movable block B, with a hole b made through it, in combination with a link E, having the head D formed on it, substantially as and for the purpose specified.
